Lignite - Wikipedia

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content. It has a carbon content around 60–70 percent. It is mined all around the world and is used almost exclusively as a fuel for.

Photo of the Week: Briquetting Lignite Coal (“Brown Coal”)

This week's photo is of a lignite coal (also commonly called “Brown Coal”) briquetting machine for a customer in Europe. Briquetting is a process used to enlarge particles such as dusts and powder. The granules are formed using extreme pressure via a double roll press. Briquetting is an environmentally friendly.
